ABSTRACT:
A middle ear prosthesis comprises a piston adapted to extend through an oval window when implanted in a human ear. A pair of jaws engage an ossicle when implanted in a human ear. A spring is coupled to the jaws for biasing the jaws toward one another to provide clamping pressure. The jaws are in turn connected to the piston.
